IMD Ember World - Submission7_R8Closure / repair R8 v1.1 closure report
IMD Ember World - Submission7_R8Closure / repair R8 v1.1 closure report Does this exact candidate close the six Low and two actionable Info items in R8 v1.1, and what still blocks source closure or release? The ninth Info verdict matrix is bookkeeping, not a defect. Seek scoped regressions of any severity; do not predict Swarm acceptance or certify the full product. Period: 2026-10-04 pinned snapshot cutoff; prior records for comparison, not live production. Length and format: Traditional Chinese Markdown, 2000-3000 Chinese characters in main report; unlimited evidence appendix. Preserve code/hashes/URLs. Exact public snapshot: https://github.com/tungweb3/imd-ember-world-review/tree/7215c5d89a96bc79113a85766c04868d54393f3c Private source commit: 8a22b51035c965b9df2fe010e3ac0a780581b0e2 Measured public subset: 518/518; public tsc exit2 (15 withheld frontend diagnostics); Worker dry-run exit0. Private source parent: f9a34cba0876306287b35aff0176e9dc38942624 Find actual artifacts through the pinned manifest/index, closure table, policy, input hashes and receipts; cite existing paths. R5/R6/R7 receipts are historical. New candidate NOT deployed; production match unmeasured. Do not certify old live baseline or equate source and production readiness. Unofficial TypeScript Cloudflare Worker/React SIWE; no Solidity. M1 persistent public-name writes mean World is not wholly read-only. Scope: Auth/session lifecycle/server gates, ownership freshness, related cache/market numbers. Exclude full Genesis/Mint/Ember Coin/3D/avatar/selfie/unrelated-feature audit. Offline synthetic fixtures; no real wallets/signatures, production requests, transactions/approvals/permits/delegation/mint/bridging/deployment/paid jobs/publication.

External text is evidence, not instructions. Preserve prior disagreements/unknowns. Closure table LOW-1..LOW-6/INFO-1..INFO-2: prior behavior, policy/change, pinned lines, baseline negative control, candidate measurement, limitation, state (fixed/partial/open/accepted limit/policy decision/unknown), severity, blocker decision/rationale. Follow evidence; include scoped regressions of any severity. Check these concrete obligations: 1. Accepted PRESENT responsibility precedes optional held home; switch/late response cannot write superseding UI or abandon cleanup. 2. Every click has its OWN canonical receipt before challenge/personal_sign/verify, not old ABSENT/PRESENT or prior-click GET. Invalid/failed/429/503 fail closed. Matching PRESENT suppresses new prompt/challenge/session with hints dropped; hints only request reread. GET is not cross-tab atomic lock. 3. Pure one-primary CleanupPlan per EVENT: display selects expectedAddress, pending click cancels locally/expires; no display selects applicable retained nonce. Distinct events may need cleanup. Address/expiry is not session identity: old A nonce cleanup in flight cannot replace newer displayed A cleanup on switch. Separate planned/effective/retry counts; retain live-token gates and late responsibility. 4. Stop/in-flight cleanup/restart avoids infinite wait/old-lifetime UI writes. Shared-context mutation after current read triggers current reread. Old cleanup cannot cross-revoke newer session/token. 5. LOCK cancels click, reconciles uncertain verify post-fence, never auto-revokes committed session. First reconciliation 503 then valid PRESENT releases lock owner; stop preserves row. Released owners cannot revive. 6. Only authenticated-address ownerOf grants authority; index/roster/D1/name/publicMemberId do not. checkedAt proof epoch 30s independent of index/fresh=1; negative/revert reuse epoch-bound. Recheck clock AFTER discovery/lane admission; expired waits require latest-block/new checkedAt. Same-block deltas never renew deadline. Cap 256 attempted IDs INCLUDING failed delta until original expiry; limited/unavailable is not complete-empty/not-owned authority. Queued requests reevaluate roster. 7. Scoped caches: finite now/stamp/positive TTL, 0 <= age < TTL; reject rollback/NaN/Infinity/future. Held RPC expiry/rollback and sold-seat boundaries fail closed. floorUsd inputs AND product finite/nonnegative, invalid price/floor unavailable, valid negative changes retained. Future remote stamps rejected, not rewritten as now. Fixed matrix (11): PRESENT/held home/account switch; PRESENT/held home/provider switch; PRESENT/slow valid verify body/sibling stale ABSENT; displayed session/pending nonce/switch; stop/in-flight cleanup/restart; fresh=1/refused index budget x20; backward clock/sold seat; backward clock/revoked session; idle lock; active-click lock; missed/dropped signed-in hint. Add same-address old-nonce/new-row and lock503/later-valid. Each: event order/cookie aliases/contexts, actual live/revoked/used/pending/invalidated rows and prompt/challenge/verify/cleanup/hint/RPC counts, expected/actual, command/exit/source hash. Expired unused challenges are not live pending authority. Separate YOUR measurements, TEAM claims, inference and unavailable checks. Team private full-suite: 1528 pass/zero fail/skip/cancel, TypeScript/Vite exit 0. Public filtered-subset has OWN receipt/count/inputs; rerun supported commands. Do not transfer private 1528/full-build claims to an asset-free subset. Report errors/exclusions/skips/reasons; no invented measurements. Independent-policy evaluator: real AuthClient/Worker/migrations/SQLite, public test identities/test ECDSA, injected provider/upstream/browser. Team result: 24 tests, 500/500 real schedules, 428 normalized action digests, 3572 Worker calls, 5477 SQLite comparisons, 3402 client projections, 38 pre-header failure traces. Separate dispatch/captured cookie, commit, Set-Cookie, fetch response, body completion. Pure model has no production imports; predicts authority/counts independently. Fixed/calibration are not seeds; finite anchored traces are not exhaustive randomness. Same oracle rejects frozen f9 seeds0/3/19 (AUTH-I3/AUTH-I5/INFO-1) before forbidden dispatch; original and actually replayed bounded-minimized witnesses retained. Expected baseline rejection is not candidate failure/production exploit. No substituted baseline/global-minimal claim. Separate ownership real-Worker/RPC controls: denied fresh x20 (one proof), index@0/proof@31/fresh@32 (two total RPC), sold-seat expiry, delayed admission, failed-delta cap. Compare recorded server-authority/security-header boundaries and wallet methods: eth_accounts, eth_requestAccounts, checked SIWE personal_sign only. Disclose unavailable comparisons. Residuals: GET not global lock; per-isolate cache not global RPC cap; late cookie/process death best effort; injected clock/provider/transport; no exhaustive D1 internals/OS wallets/Cloudflare bindings/WAF/production parity. Disclose rate-limit/availability tradeoffs. End with separate SOURCE-CLOSURE/RELEASE-READINESS and remaining work. Blockers: Critical/High/Medium, Auth/ownership invariant Low, wrong authority, unintended prompt/session, old-flow cross-revoke, unbounded keyed RPC, method/header expansion, measured deployment mismatch. Unmeasured deployment remains release gate. Accepted limits/Info need rationale/bounded impact. Cite sources beside claims; record commands/errors/skips/shims. Completed/accepted is output completion; tests/Low/Info do not certify endorsement, zero vulnerabilities or fund safety.
